INSERTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 582,331, dated May 11,1897. Application filed December 14, 1895. Serial No. 572,160. (Nomodel.)

To aZZ whom it may concern.

Be it known that I, RoDoLPH WIRTH, a citizen of the Republic of France,residing at Chicago, county of Cook, State of Illinois, have invented acertain new and useful Improvement in Inserting-Machines; and I declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art-to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to machines for inserting and clenching lacefasteners, and is particularly designed for use in inserting andclenching the form of lace-fastener set forth in Patent No. 559,463,issued May 5, 1896, to Charles H. Pratt.

The object of the invention is to provide a machine of simpleconstruction and economical in manufacture which will rapidly andefficiently insert and clench the lace-fastener.

The invention, consists, substantially in the construction, combination,location, and relative arrangement of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawings, andfinally pointed out in the appended claims.

Referring to the accompanying drawings, and to the various views andreference-signs appearing thereon, Figure 1 is a View in centralVertical section of an apparatus embodying my invention. Fig. 2 isadetached detail View, in front elevation, partly in vertical section,of the plunger. Fig. 3 is a View in side elevation of the constructionshown in Fig. 2, partly in vertical transverse sections. Fig. 4 is abroken detached detail view, in vertical section, of theclenching-plate. Fig. 5 is a View in end plan of the lower end of theplunger shown in Fig. 2. Fig. 6 is a detached side view of the form oflace-fastener to which my invention is particularly adapted before theends thereofare clenched. Fig. 7 is a similar View after the clenchingoperation.

The same part is designated by the same reference-sign wherever itoccurs throughout the several views.

In carrying out my invention I provide a suitable framework or stand Aof sufficient size and convenient arrangement to support the operatingparts of the machine. Mounted upon the stand A is the head B,having abearing J formed therein adapted to receive the plunger K, whereby saidplunger may slide back and forth in said bearing. Any suitable orconvenient means for effecting a reciprocation of the plunger K may beemployed. I have shown a simple and convenient arrangement foraccomplishing this result wherein I provide a pivotally-mounted lever 0,having the free end thereof arranged to be received in a seat is, formedin the plunger K. The lever O is arranged to pass through a block D,carried by a rod E, said rod arranged to pass through a suitable flangeor partition 19. A spring F is interposed between said flange orpartition I) and said block D, the tendency of said spring being tonormally maintain the lever O in position to hold the plunger K in onelimit of its movement. The rod E is connected to a conveniently-arrangedlever H, such as a foot treadle, through a suitable connection G,whereby said lever C may be rocked against the action of said spring Eto move the plunger K to the other limit of its movement.

The lower end of the plunger K is provided with central sockets adaptedto receive the removable parts 70 of a size adapted to receive thereonthe fasteners to be inserted. The plunger K is provided with acountersunk seat It in the end thereof surrounding the posts k and of ashape and depth adapted to receive therein the coils or convolutionsforming the body P of the fastener. At a point adjacent to the seats 70the wall of the plunger 7c is cut away, as clearly shown at k in thedrawings, and a spring 70 is held in such cut-away portion, as by meansof a screw In and having its end arranged to project slightly into theseat 71;, whereby the fastener P,when once placed in position in theseat 10 and surrounding the pin or post 10 is held in place and isprevented from falling out.

The head or portion B of the framework is provided with a projection M,and removably mounted in a seat formed in said projection and in theline of movement of the plunger K is what I shall term the anvil N,arranged to cooperate with the plunger K to effect a clenching of thefasteners after inserting the same in the material or article to whichthe fastener is to be applied.

By reference to Figs. 6 and 7 of the drawings, and also to the patentabovementioned, it will be seen that the fastener is formed of a singlestrand of wire bent into convolutions to form the body part P thereofand having the ends 19 bent into preferably right-angular gular relationwith respect to each other on the inner side of the article, as clearlyindicated in Fig. 7 ingof the said ends in the manner and directionindicated, I provide in the anvil N a pair of depressed seats a or,adapted to respectively receive the ends of the fastener. The said seatsor depressions present a curved or concaved surface to the ends of thefastener and are arranged to bend the ends 13 in the desired relativedirections, as clearly indicatedin'Figs. 2, 4t, and 7. The postaccomplishes the important'function of clenching or slightly upsettingthe extreme points of the ends 19 of the fastener, thereby preventingsaid ends from being forced back through the material or article to forman obstruction to the lace while being secured in or released from thefastener, and this is a material and beneficialfeature of my invention.

It will be observed that the plunger K is shown double-that is, asprovided with two clenching-posts k and two seats k and holding springs7;. It will also be seen by particular reference to Figs. 2, 4c, and 5that the two portions of the plungers are respectively arranged forright and left fasteners, for it will be understood that a rightfastener is required on one side of the material or article and a lefton the other side, and therefore a right and a left may be applied tothe material or article simultaneously upon a single operation of themachine. It will be distinctly understood, however, that I do not limitor confine myself to such specific construction and arrangement, as manyvariations and alterations therefrom would readily suggest themselves topersons skilled in the art and still fall within the spirit and scope ofmy invention.

The operation of the machine will be readily understood from theforegoing description.

Having now set forth the nature and object of my invention and a form ofapparatus embodying the same and having explained the construction andmode of operation of such apparatus, what I claim as new and useful Inorder to effect the bend-' and of my own invention, and desire to secureby Letters Patent of the UnitedStates, is-

2. In a machine for inserting and setting lace-fasteners a plungerprovided with a seat inthe end thereof, adapted to receive a fastenertherein, and having a clenching-post arranged in said seat, said plungerbeing cut away adjacent to said seat, a spring mounted in said cut-awaypart and having its end arranged to project into said seat to hold thefastener therein, an anvil arranged in the line of movement of saidplunger and pro vided with concaved depressions arranged relatively toeach other to engage and bend the ends of the fastener into angularrelation with respect to each other; as and for the purpose set forth.

3. In a machine for inserting and setting lace-fasteners, a plungerprovided with a seat in the end thereof, adapted to receive a fastenertherein, a clenching-post inserted in the end of said plunger and havingits end arranged to project into said seat, means for retaining afastener in said seat, a removable anvil arranged in the line ofmovement of said plunger and provided with angularlyarranged concavedepressions, and means for reciprocating said plunger; as and for thepurpose set forth.

4. In a machine for inserting and setting lace-fasteners, a plungerprovided witha seat adapted to receive a fastener therein, an anvilarranged in the line of movement of said plunger and adapted to beengaged by and to bend the ends of the fastener upon the under side ofthe article to which the fastener is to be applied, a clenching-postarranged to upset the points of the bent ends of the fastener, wherebysaid bent ends are prevented from being forced back through the article,and means for reciprocating said plunger; as and for the purpose setforth.

In testimony whereof I sign this specification in the presence of twowitnesses.
